13. Wing Flap Damage Criteria (Corrugated Skin Flap)
A. Negligible damage: Any smooth dents in the flap skin that are not more than 0.050 inch (1.27 mm)
below contour and circumscribable with not more than a 1.5 inch (38.1 mm) diameter circle - that
have no evidence of skin tears, cracks or skin penetrations and which do not include corrugations -
constitute negligible damage.
B. Repairable damage: Dents or dings deeper and/or larger than specified may be repaired. Skin tears,
cracks or penetration must be repaired. Dings that include corrugations are unlikely to be reworkable,
but may be repaired by replacing the damaged area. Corrugated skin material is available from
Cessna.
C. Damage Necessitating Replacement Of Parts: Multiple repairs to the same area must not be made,
but a larger repair incorporating both repairs may be made. Decisions regarding replacement of parts
should be made based on the feasibility of repair verses complete replacement of the skin
14. Wing Flap Damage Criteria (Model 206 Flap)
A. Negligible damage: Any smooth dents in the flap skin that are not more than 0.030 inch (0.76 mm)
below contour and circumscribable with not more than a 1.5 inch (38.1 mm) diameter circle - that
have no evidence of skin tears, cracks or skin penetrations and which do not include corrugations -
constitute negligible damage.
B. Repairable damage: Dents or dings deeper and/or larger than specified may be repaired. Skin tears,
cracks or penetration must be repaired. Dings that include understructure (ribs) must be repaired
by reforming or removal and replacement of the rib. Reevaluation of the skin after the repair of the
understructure will determine if the skin damage is negligible, repairable or replacement damage.
C. Damage Necessitating Replacement Of Parts: Multiple repairs to the same area must not be made,
but a larger repair incorporating both repairs may be made. Skins must be replaced if damage extends
across more than one rib.
